Refractory Materials For Casting

● Zirconia ceramic foam filter is made of high-purity, high-quality zirconia, with a unique formula and advanced environmental protection technology. It has a unique three-dimensional uniform pore structure, withstands temperatures up to about 1700°C.

● The size are available in square, round and custom geometric shapes; sizes ranging from 10mm up to 600mm, and thicknesses from 10-50mm. zirconia ceramic foam filters are designed for filtration of carbon steel, steel alloy and stainless steel.

● The three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. The three-way catalytic reactor is similar to a muffler. Its outer surface is made of double-layer stainless steel sheet in a cylindrical shape. A heat-insulating material-asbestos fiber felt is installed in the double-layer sheet sandwich. Inside, there is a purifying agent in the middle of the mesh partition. The purifying agent is composed of a substrate and a catalyst. The main function of the 3 way catalytic converter is to convert harmful gas into harmless gas, which plays a role in protecting the environment. It is installed in the exhaust pipe of a car, close to one end of the engine. After the exhaust gas is discharged, it is converted through three-way catalysis. After the exhaust gas is converted, it is discharged outside the car.

● The square sampling cup is for determining the Carbon equivalent, % Carbon and % Silicon in molten iron by using the  principle of thermal analysis.Cups are available in square and round shape.500 degree Celsius to produce “resin bonded sand”. This resin bonded sand is shot into the pre-heated mold with having the K-type thermocouple tube inside. At the temperature of 250 degree Celsius, the cup is formed by the resin bond. This cup is coated inside with silica for being thermal insulation and then filled in the cup with 15 gram of Tellurium. By means of drying this coated cup at the temperature of 80 degree Celsius for 4 hours, the carbon cup is ready for the casting control.

The Diesel Particulate Filter (DPF) is specifically engineered to remove black smoke (referred to as particulate matter or PM) from the exhaust of diesel engines, significantly contributing to cleaner emissions from diesel vehicles and garnering considerable interest from manufacturers worldwide. The most effective design is the wall-flow filter, which removes particulate matter through physical filtration utilizing a honeycomb structure, akin to an emissions catalyst substrate, but with alternate ends of the channels blocked. The DPF is ideal for purifying exhaust gases from a variety of diesel vehicles and marine vessels. We offer DPFs made from various materials, including cordierite and silicon carbide.

● The Round sampling cups are used matching with the carbon and sulphur analyzer to quickly analyze carbon content, silicon content and carbon equivalent in molten iron.The carbon cup is made of resin coated sand, straight quartz tube, T1 and T2 thermocouple wires and Sealing cement and other components. When the molten iron is poured into the sample cup, the molten iron gradually solidifies with time. The thermal analysis measures and calculates the CEL, C, Si and other components according to the temperature platform of the cooling curve.

A fast-response, non-splashing thermocouple with a protective cotton tube is utilized for measuring the temperature of molten metal.

This expendable thermocouple consists mainly of a temperature probe and a large paper tube.

The positive and negative wires of the probe are welded to compensation wires housed in a bracket encased by a smaller paper tube.

The hot wire is supported and protected by quartz, while the temperature probe is topped with a lid to prevent scum buildup.

All components are positioned at the thermocouple's end and secured together with a refractory filler.

● The infrared honeycomb ceramic burner plate is mainly used for gas infrared burners. It is a porous ceramic honeycomb panel, which is attached to the catalyst as a combustion furnace, and is designed by using advanced science and technology. The result of ideal combustion-the catalytic combustion of methane gas can burn more fully, maximize gas energy, and reduce flue gas pollution (CO <0.02% NOx <10 ppm), fully complying with national environmental standards. Such a ceramic plate improves the simple plane corrugated three-dimensionality through the surface of the honeycomb ceramic plate, increases the specific surface area and the combustion area, thereby playing the role of regenerative combustion, so as to achieve more complete combustion of the flame seedlings to reach the infrared burner. Heating effect, in order to achieve low power consumption and high environmental requirements.

● Rapid immersion thermocouple is widely used for measuring the temperature of molten steel, molten iron and other molten metals. Our platinum rhodium sensor is synonymous with accuracy and reliability, and is regarded as an industry standard worldwide. Variations in length, slag cover and thermocouple type can meet customer's precise requirements. It is mainly composed of a thermocouple head and a large paper tube. According the different thermocouple connector, thermocouple tip can be classified as 604, 602, HR and Or type.

● Honeycomb ceramics as a carrier is the key part of three-way catalytic converters. The honeycomb structure with thousands of parallel channels forces the exhaust gas into a turbulent state, resulting in more Good exhaust effect The contact between emissions and precious metals improves the mass transfer conditions and improves the conversion efficiency.Therefore the cordierite ceramic honeycombs have been developed as substrates for automotive catalytic converters to solve the environmental pollution problems.

● Fiberglass mesh filter are manufactured with high-temperature-resistant fiber, further more, they are produced by special technique and following-process, so with special technology and stable quality.Fiberglass mesh filters are designed for filtration of molten steel, which can effectively remove slag,refractory particles and non-metallic inclusions from molten metals.

● High Silica fiberglass mesh filter is also called refractory cloth filter. It is woven from high-silicon glass fiber yarn and coated with a special resin. our fiberglass mesh filter are widely used in aluminum alloy and copper alloy. It can also be used for chemical liquid filtration and high temperature gas filtration.

● High silica fiberglass mesh filter is weaved by high silica fiberglass yarn and coated with special refractory coating.Silica mesh filters are ideal for in-mold filtration of gray, malleable, white, compacted graphite and ductile cast irons.The filter screen can be cut into squares of any size with scissors, placed under the sprue cup, on the lap surface of the runner, and on the lap surface of the runner and the inner runner, and press it with a box.
