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:does furnace use refractory cement to make refractory bricks?
- use refractory clay, refractory clay is made of refractory clinker clay mixing with cornstarch in a certain proportion, generally refractory cement refers to alumina?cement, which is generally used in castable refractory, producing binder.
- Q:Can mud and salt be used as refractory materials
- Clay can be used as a refractory material, but salt can certainly not be used.
- Q:High alumina refractory bricks (Universal arc) weight for hot metal ladle
- Climbing, C23B ladle generally use T3 ladle bottom brick, brick wall with C23 package, C231 Some permanent layers are built from high alumina bricks, and some are built from castable refractory, T82, T43. Specific size can be checked according to the type of brick
- Q:What is refractory brick? What is refractory clay? ?
- Refractory brick is a kind of brick that is fireproof, refractory soil is the soil that is fireproof
- Q:What is the heating temperature in the test method of thermal shock resistance of refractory bricks
- 1, quenching (air cooling or water cooling), after the completion of the specified number of times. 2, maintain 20min, introduce the following types briefly. 3, repeated testing and record the times of the material produces macro cracks. The thermal shock resistance is shown by the times of thermal cycle of damaging half of the heated end face, quenching(air cooling or water cooling ) there are many expressions and testing methods of the thermal shock resistance, and then dry. Put the heating end surface of standard size brick((200~230mm) X (100~150 m K (50~100mm) claw)into the preheated to 1100 DEG C 50mm in furnace, quenching (air or water), then quenching in room temperature water for 3min, measured the maximum temperature of sample surface produces cracks. After the temperature of the material rises to a predetermined temperature, the ratio of residual anti-bending strength and anti-bending strength at room temperature before heat shock, after the material rises to various temperatures, measure its strength retention rate.
- Q:is there any requirement for radioactive materials in refractory materials.
- they all do not cause radiological hazards to the environment, so no requirements! analyze rom the element , magnesia. Do not know if it is useful, but material used by refractory materials, firstly any chemical elements are radioactive, human beings can not close, then, such as silicon dioxide: If it is radioactive. analyze from use, such as bauxite, does not have the use value
- Q:When the coal-fired steam boiler is built, it is necessary to build a common red brick between the refractory bricks. May I ask what is the requirement for this common red brick?
- The same the better, it will be easy to build
- Q:What is the size of mechanism brick and general refractory brick?
- The ordinary refractory brick is 230mm long, 53mm thick; red brick is 240mm long, 115mm wide, 65mm thick,
- Q:What is the difference between the refractory bricks, hand-made bricks and the machine pressure bricks?
- Hand-made brick mainly produces brick that is not easy to produce molding Machine pressure brick adopts 100 tons of press machine to mold the density of hand-made brick is not enough, it's light; machine pressure bricks can only produce bricks that produce molding at a time, hand-made bricks mainly adopts hydraulic vibration molding machine
- Q:The boiler is divided into several categories according to the structure, what characteristics does each have?
- package boiler and assemble boiler are divided into vertical boiler and horizontal boiler. Vertical boiler. Assembled boiler adapts to boiler more than 6 tons, the package adapts to boiler less than 10 tons.
