The fiberglass needled mat is made from alkali-free glass fiber yarn as raw material, with a single fiber diameter of 7 to 9 micrometers. The fibers are cut into short lengths ranging from 6cm to 9cm, and then subjected to carding and decomposition to create an extremely fine felt-like material. This material is then fed into a needle punching machine, where it is continuously stitched using thousands of needle punches. Its main components are silica, alumina, and calcium oxide. What are the features of a fiberglass needled mat? It exhibits exceptional properties such as heat resistance, tensile strength, durability, fire resistance, corrosion resistance, and electrical insulation. It also offers outstanding insulation, sound absorption, and dust removal efficiency surpassing that of fabric filters. Where is the fiberglass needled mat used? The fiberglass needled mat is usually used as thermal insulation for such domestic appliances as barbecue grills,electric ovens, microwave oven, coffee cooker, water heater and other appliances need better energy effiency and less cooking time. Available in rolls or die cut pieces based on buyerâ??s drawing and request. The fiberglass needled mat can also be laminated or fabricated with foil facing, aluglass cloth facing, stitched with glass fabric or glass fabric bag, or coated with self adhesive Small sample pieces are available free based on request and freight to collect.

It is applied during the steelmaking with low cast iron content (allow of steel and carbon) in charge in oxygen converter and electrosmelting processes. In metallurgy carbon raiser (milled graphite) is widely used for slag foaming, during coal graphite production, as a filler for graphite-reinforced plastic.

Semi coke is made from high grade Jurassic coal as a new type of carbon material. Semi coke produced in China, and main production city in Shaanxi China. Semi coke can instead of metallurgical coke to be used in producing ferroalloys products. Semi-coke is light black, characterized by high fixed carbon, high specific resistance, high chemical activity, low ash content, low sulfur and Low phosphorus. It is wildly applied to chemical industry, metallurgic industry, and gas- making industry to produce Ferroalloys, ferrosilicon, Ferronickel ,Ferrochrome, FeMn & SiMn, as well as Calcium carbide and, fertilizer, etc. F.C.: 84% min Ash: 8% max Volatile matter: 8% max Sulfur: 0.35% max Moisture: 18% max Semi coke is made from high grade Jurassic coal and as a new type of carbon material. It can be instead of some metallurgical coke when produce ferroalloys products. Using semi coke during steel making, blended the semi coke with met coke, which reduced their cost 20% to 30% than using met coke only. Advantage of semi coke than Met Coke in production of Ferro-alloy smelting as deoxidizer (1). Semi Coke could improve the quality of the ferro alloy significantly (especially low aluminum alloy Al2O3â?¤0.1%). (2). Semi Coke could reduce unit electricity consumption significantly (nearly save more than 1000 KWHR, that means 8-10%) (3). Semi coke could lower the cost of raw material. Although the price of semi coke and coke is similar, but its far cheaper than charcoal and pet-coke (4). Its very simple to replace coke, pet-coke and charcoal with semi coke. Its no need to upgrade your equipment and the operation is easy and process is simple.

Foundry coke is widely used in iron making because of its special physical and chemical characteristics. It's the main cupola molten iron fuel, foundry coke plays an important role in melting furnace charge and overheat the molten iron, support stock column, maintain good air permeability. Therefore, foundry coke with large size,low reactivity, low porosity, sufficient impact resistance and crushing strength, low ash and sulfur content, it is popular in the international markets.

Description of Calcium Aluminate Cement Calcium aluminate cement, alumina cements or high alumina cements are obtained by the reaction at high temperature of lime (from limestone) and alumina (contained in natural minerals like bauxite). The aluminate cement obtained after cooling is a hard mineral: calcium aluminate clinker. Ground into a fine powder, the clinker becomes calcium aluminate cement (CAC) which forms a paste when mixed with water. The aluminate cement has the ability to harden very quickly: it forms a rigid solid within 24 hours. Application of Calcium Aluminate Cement There are two distinct ways to use calcium aluminates: as high-performance binders and as mineral reagents in a variety of industries. As binders, calcium aluminates are used in concretes and mortars for specialized applications for their properties of resistance to corrosion, abrasion and heat combined with rapid hardening and the ease of controlling grading variations. Calcium aluminate cements are also used in combination with other fine components. Hydraulic binders with new properties are then obtained. In this way, the calcium aluminate powder acts as both a complex hydraulic binder and a mineral reagent interacting with the other components in the mix. As reagents, calcium aluminates are found in non-hydraulic systems. This is the case in metallurgical treatments (iron and steel industry, foundry) where specific grades of calcium aluminate are used for their low-temperature melting properties and for trapping molten metal impurities.
