Q:Should kiln be warmed before the ignition of the new furnace?
If you don't have to heat up the furnace. The new furnace must be heated up, and the temperature should be increased according to the heating-up furnace curve, so the current situation you meet is appeared
Q:Which is best of refractory brick press machine?
Rub press machine have been forced out. Without permanent magnet. The electric screw press machine is suitable for the forming of refractory bricks. Use Kehui switch reluctance to servo motor to drive electric screw press machine, have the ability of high quality electric screw press machine, no water cooling, high efficiency and energy saving, green and environmental protection.
Q:can castable refractory replace refractory bricks in rotary kiln?
Rotary kiln has special casting material, completely can replace the refractory brick.
Q:Shale brick and clay brick? Answer before you know it
Is the shale as raw material for high temperature baked bricks using shale and coal gangue, shale sintered porous brick, hollow shale brick, shale brick, high insulation, water wall and other types of modular brick.
Q:What are the type, location and the physical and chemical effects of the refractory brick used in the cement rotary kiln?
But most people use high alumina brick or clay brick, G6 refractory brick. The specific masonry location, such as G4 refractory brick, standard brick, T38, OD, T39, according to the length of your rotary kiln, many kinds of refractory bricks are used in cement rotary kiln, the specific size of the inner diameter should be calculated in detail
Q:What is the role of refractory brick, whether is there any books to introduce refractory bricks
Refractory bricks are generally used to build a hearth. Such as, boiler, furnace (molten metal), air heating furnace etc, the furnace need refractory bricks to bulid.
Q:Do refractory bricks insulate heat?
Refractory bricks have a certain ability of heat insulation, but its thermal insulation is far less than that of glass fiber and wool.
Q:Classification of refractory bricks
Q:What are the release agents of refractory bricks?
Alkalinity, the production process of alkaline, acid and alkali resistant transparent instant thickening powder, you can adjust the proportion according to the cost and needs of quality, environmental protection: One: Add the preservative into water to mix, after soaking one hour, then mixing evenly the production ratio, and then add the super core release agent into water to mix, add flavor pigment masterbatch into water to mix with water mixing, ensure completely dissolved, then add the waste oil, falvor is appropriate amount= release agent. Two, the newest recipe of release agent super core release agent masterbatch, waste engine oil, water, instant acidproof and alkaliproof transparent thickening powder, wire drawing powder, preservative, flavor and pigment= release agent super core wire drawing powder with water mixing, it is the most newly developed special core masterbatch and engine oil of Chengdu Hengfeng Hongye detergent factory, and it doesn't contain toxic solvents, especially 1, it has the following features, after thickening more than half an hour or so, mix evenly is ok, in a few seconds will waste oil and alkali: 10% of waste engine oil, 20% of release agent core masterbatch, 88% of water, 500g instant acidproof alkaliproof transparent thickening powder, 80g wire drawing powder, 1g pigment and preservative and lubricating oil and industrial grease, these integrate with water.
Q:The harm of wet bricks used in refractory bricks
Increase the natural protection time, increase the baking time, or water can not discharge, this will cause swelling deformation of furnace wall.
