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.

Q:Why are the refractory bricks near to rotary kiln tyre easy to be short lives?
Q:When using high alumina refractory brick, what are the reasons leading to the decline of the performance of high alumina brick?
The excess air coefficient is controlled in 1, in order to prevent producing water cracks in the production of high aluminum refractory brick from, control the water absorption of 2 grade clinker of bauxite with high alumina below 4%-5%. 1-1,the water absorption of the tube mill should also be controlled below 6%, and adjust thermotechnical, making the high alumina refractory brick burning be in the stable weak oxidizing atmosphere. should be 2
Q:can the refractory sand be used to make refractory bricks?
No...
Q:Why can't build refractory brick behind the skew block?
refractory is heat expansion and cold contraction, it is also called refractory brick, can resist high temperature up to 580-770 degrees. Mainly used for the smelting furnace. faint yellow or brown, when it is high temperature, it will squeeze toward the center. Refractory material made of refractory clay or other refractory raw materials. the shortened form of fefractory brick is brick. vault will be extrusion deformation. Refractory material with a certain shape and size
Q:the amount of per square refractory brick of Various specifications and thickness of the refractory brick wall
9 grams-47. 7 grams- 47 calculate by your own according to the actual volume; cubic centimeter; 2.2 grams Clay brick 2: 1; 3, high alumina brick 3; cubic centimeter; standard density, cubic centimeter: 230mm * 114mm * 65mm, diatomite insulation brick 0, you can calculate the reference value
Q:Classification of refractory bricks
Q:Why are clay bricks used when buildings are below zero? Frost heaving, water absorption, or something?
The clay brick has a certain strength, and has better heat insulation and sound insulation performance, and the interior wall of the winter can not appear condensation phenomenon, and the price is low. Although a variety of new wall materials are emerging, clay bricks will still be used as a main material for masonry work in the future
Q:Do refractory bricks insulate heat?
The light brick inside the brick is heat insulation brick, according to the different bulk density, the effect is also different
Q:What kind of refractory material is used in the furnace when the boiler reaches more than 1200 degrees?
except refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and so on.
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.
