High carbon ferrochrome melting point of about 1550 ℃. In order to make successful eduction of slag, iron, molten iron to overheat 100 ℃ in the process of production, so the slag melting point 1650 ℃. If the slag melting point is low, the temperature in the furnace is also low, the slag discharge, but hot metal because of the small and difficult to discharge superheat, appear out of the iron slag is much less phenomenon, serious when slag not only iron, this will cause a great loss.
High carbon ferrochrome slag is high quality class basalt properties of building materials. Its processing with the all kinds of concrete, has the advantages of other stones do not have. High carbon ferrochrome slag processed into rubble, has the characteristics of high strength and special rough surface. High carbon ferrochrome slag gravel, under the condition of water absorption and pore its strength will be greater than the limestone, which is similar to basalt.
High carbon ferrochrome slag with hole, and a good strength, is conducive to absorb heat in the process of concrete hardening of variant. High carbon ferrochrome slag gravel has good resistance to JianJiLiao reaction. So say: high carbon ferrochrome slag after processing is undoubtedly a good building materials, is also a new type of building materials.
