How to choice refractory material for induction furnace lining

refractory material

In the coreless furnace, a core induction furnace, as the IF refractory material for induction furnace for melting gray cast iron, ductile iron, malleable cast iron, vermicular graphite cast iron and, as well as the use of refractory materials, Cast iron alloy, molten carbon steel, alloy steel, high manganese steel. IF Medium frequency induction furnace refractory supplier lining materials selection must have the following characteristics:
1. In a sufficient temperature, no deformation, no melting performance
2. Can have the necessary structural strength at high temperature, and does not produce softening deformation
3. Must be stable at high temperature, does not cause expansion and contraction leading to cracks
4. When the temperature changes drastically or unevenly, it will not break and peel off
5. Can resist the metal solution, slag and furnace gas and other chemical erosion

Mainly divided into the following types of refractories: acid induction furnace refractory china lining materials, the use of high-purity microcrystalline quartz sand, powder, adding high-temperature sintering agent and mineralizer mixture of dry vibration material, strictly control the size and sintering agent added, So no matter with a variety of knotting methods can be obtained dense induction furnace refractory lining material. The product is mainly used for foundry ash iron, ductile iron, carbon steel melting process, but also for continuous high temperature environment, can also be used for titanium and high temperature non-ferrous metal smelting. Neutral lining material is made of corundum sand, powder, adding aluminum magnesium spinel powder and sintering agent and other mixed dry powder material. The particle size distribution in line with the maximum bulk density theory, so through a variety of knotting methods can be obtained dense uniform lining, mainly used for a variety of alloy steel, carbon steel, stainless steel, this material has good thermal shock stability, Sexual and high temperature strength, and in normal use to keep the backing of a certain loose layer. Induction furnace refractory supplier refractory lining materials are made of fused or high-purity magnesia, powder, adding aluminum-magnesium spinel powder and sintering agent. The particle size distribution in line with the maximum bulk density theory, so through a variety of knotting methods can be obtained dense uniform temperature lining, mainly used for a variety of high alloy steel, carbon steel, high manganese steel, tool steel, stainless steel, the material has a high Refractoriness and high temperature strength, and in normal use to keep the backing of a certain loose layer. Coreless induction furnace refractory material due to the role of mineralizer, through the first oven sintering a-phosphorus quartz conversion rate is high, so the oven time is short, with high volume stability, thermal shock stability and high temperature strength, In normal use is backing to maintain a certain degree of loosening.
