2015615The current commonly used arc furnace, furnace wall and bottom furnace, the hot spot is the weak link of electric arc furnace. Reasons for damage of the refractory at the top of the one is splashes, furnace dust erosion; second is due to the high around the electrode temperature, top temperature difference larger caused by
Best Refractory Bricks For Sale. Shopping for specialty items like fire bricks is tricky, as such, I have tried to compile the refractory bricks (soft, hard, IFB) that are sold on amazon and are good for most projects. This is not an exhaustive list, nor does it cover every forge / foundry design. Despite this, I think these are useful products.

2011528Since I have 3" wall total thickness to work with to get the bore size I want, I have been thinking of just sticking with the 3" castable wall and adding an insulating jacket around the outside of the furnace. Most of my pouring will be bronze but I want to try out iron. My first furnace did get hot enough to melt it.
Clay refractory bricks are the most widely used refractories made from chamotte clay minerals and calcined at a high temperature of 1300 to 1400 ° C.. It can be easily located out in the nature and contains suitable content ratio of silica, cyanite and alumina. Fire clay bricks have low porosity and are durable for various re-heating process.
The refractory walls of furnace and kilns attacked by the shock effect of gases and high-velocity abrasive raw solids flow over them. Therefore, the refractory must have good wear resistance. Thermal properties 1. Melting point It should have very high melting point. 2. Thermal expansion

Melting furnaces: depending on your furnace design (tank, top charge, sidewell, CIF, etc.) a full range of monolithic or brick solutions can be offered; The solution will be zoned to fit the furnace process conditions: chamber temperatures peaks, alloys processed, mechanical abuse from the charge and skimming, usage of salts / fluxes
of the furnace either is rammed or lined with refractory bricks. For side wall lining a suitable cylindrical former is essential. The former can be made either removable or consumable type. In case of consumable former the quality of the former should be compatible with the quality of the product (melt) to be produced.
Fused Cast AZS Refractory bricks products of AZS series of oxidation are made of qualified raw materials by using specially designed electric arch furnace and undergoing the casting process through long-arc melting furnace and oxidation. This kind of casting process hardly suffers any carbon pollution from the electrode
Refractory and brick materials are needed to line huge shaft-like blast furnaces in which the molten pig is formed. The auxiliary furnaces or hot blast stoves, which heat the air for the blast furnace, are also lined with refractories. The molten pig iron from the blast furnace is then sent to a brick- or refractory-lined ladle.
Kiln building refractory fire bricks, blocks, and tiles are stacked to form insulating furnaces, boilers or other thermal process vessel walls. The refractory fire bricks are usually cemented together with refractory mortar. P lease note: BRICKS SHIPPED UPS GROUND CARRY A $0.75 /BRICK PACKING FEE AND A $5.00 MINIMUM PACKING FEE.
A smaller furnace chamber will conserve heat, but you will have to fish the crucible out of the furnace so leave room for the tongs. Set the brick with the hole for the nozzle so that the torch will blow along the side wall of the furnace chamber. The hot gases coming from the nozzle are cool in the center.
