FAQ

Q1: How do you control the products quality?

A1: With strict quality control system throughout the materials selection and production process, our refractory and ceramic fiber products quality is effectively controlled to meet customer requirements.

From the raw materials selecting, our quality control begin. The quality certificates of raw materials are required and each batch will be tested before using. During production, the quality control are conducted by workers and then each piece will be sorted and examined by quality supervis

 

Q2: What`s the lead time for my order?

A2: It depends on customers’ requirements and our production schedule. And usually we need 30-60 days for refractory bricks,10-25 days for unshaped refractory materials and 10-20 days for ceramic fiber blankets.

 

Q3: Can you offer Door-to-Door delivery?

A3: Yes, but only for some countries such us U.S., UAE, Saudi Arabia, Iran, and Russia, etc.

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.
Q:how to test the high alumina refractory brick mixed alumina?
The first thing before producing bricks is to test whether the aluminum content reaches the standards, general testing on raw materials. Second: the shaped high aluminum brick will be tested in some professional equipment, you can know it from the professional inspection departments.
Q:Small size black brick can replace refractory bricks for wood burning fireplace?
No, black brick has no thermal insulation effect.
Q:What type of refractory brick won't deform or crackbe for a long time in the temprature of about 1600 degrees?
1. , mullite poly light ball brick type, andalusite brick type: MJ-1600 MJ-1700 the temperature is higher than 1600 C. 3, the refractory bricks that won't deform or crack in the 1600 degrees Celsius for a long time includs the following several commonly used bricks: GMZ-80 GMZ-75 the temperature is higher than 1650 DEG C, 2, corundum mullite brick type
Q:the refractory brick in glass furnace burner was burning, the bricks on both sides of the fire hole were burning the blocked it, what will cause brick burning?
The firebrick in glass melting furnace is mainly consisted of zircon brick, other ordinary refractory materials can not effectively prevent the erosion of glass solution. Because the glass melting liquid is eutectic mixture compared to the refractory bricks, it penetrates into the refractory brick and reduces its original performance, simply speaking, the glass melting liquid dissolves the refractory bricks as eutectic mixture .
Q:What is the advantage for ceramic fiber material compared with refractory brick?
Heat capacity; excellent thermal shock resistance, good chemical stability, bearing sudden cooling and heating, without oven heating and cooling ,high speed, energy saving, is 1/8 of refractory brick, construction is simple. ceramic fiber materials and refractory brick belong to refractory insulation materials; low thermal conductivity: Low bulk density, ceramic fiber material is a new type of lightweight thermal insulation material, is one of the 10 points of lightweight refractory brick,
Q:Can thick steel plate be used instead of the furnace inside the refractory brick?
It depends on the temperature. The steel plate is a kind of heat conduction material which hasn't heat insulation, which should be based on the working environment.
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:Whether the cement kiln refractory bricks belong to hazardous waste or not?
No, there is no harmful gas produced, and it will not pollute the ground.
Q:The shape and size of general used refractory brick
According to the national standard, the outline dimension of mechanism red brick is: length is 240mm, width is 115mm and thickness is 53mm. That is: 240mm * 115mm * 53mm. The shape and size of the ordinary refractory bricks are: Length is 230mm, width is 114mm and thickness is 65mm, that is: 230mm * 114mm * 65mm. The shape and size of special refractory bricks are: 345mm*328mm*97mm.
