- Q:What are the requirements for refractory materials in heat treatment furnace?
- Fire resistance is an important performance index of refractory materials, but it does not represent the highest temperature in actual use of refractory materials. In actual use, refractories also bear certain pressure, therefore, must consider the high strength at high temperature refractory material, which is in high temperature under certain pressure without deformation, such as the NZ-40 refractory refractory degree up to 1730 DEG C, but the maximum temperature is only 1350 degrees celsius.
- Q:What are ordinary bricks, refractory bricks, hollow bricks?
- Referred to as refractory brick. Refractory wood made from refractory clay or other refractory material
- Q:How much is one ton / ton of high alumina refractory brick?
- The market price of about super high aluminium brick price at 3000 yuan / ton, a high aluminum brick at around 2500 yuan / ton, two high aluminum bricks at around 2100 yuan / ton three grade high alumina bricks at around 1850 yuan / ton for reference, choose to buy the area is not the same as the prices are not the same.
- Q:Which is better, the soft core or the hard core?
- When the current through the wire, it will produce a magnetic field in the vertical plane space of the wire, if there is a current two wire close by in the same direction, because they produce a magnetic field in the direction is opposite, it will produce a repulsive force is due to the magnetic field force. They will mutually inhibit current intensity of the other party, caused by the reduction of current in the wire, this inhibition of each current intensity, we called wire inductance. When the AC current line frequency is high, the inductance is stronger.
- Q:What is the apparent porosity of high alumina brick?
- Total porosity is porosity refers to the total volume of sample porosity in the percentage of total volume of samples. Apparent porosity refers to the percentage of the total volume of openings, pores, and total specimens in the sample.
- Q:The difference between light high alumina brick and heavy aluminum brick
- Lightweight high alumina bricks, commonly called insulating refractory bricks, also known as insulating refractory bricks. First of all, literally, lightweight aluminum bricks and heavy aluminum bricks are very different in weight. Lightweight high alumina bricks, also called insulated high alumina bricks, are designed for insulation and heat preservation. In normal use, the utility model is not directly contacted with the furnace temperature, and is a refractory brick product which is close to the furnace wall and has the function of heat insulation and heat preservation.
- Q:What are the alloy wear resistance materials?
- According to the composition of Beijing Naimo metal materials company will wear resistant metal materials is divided into the following five categories: one: high manganese steel series: high manganese steel (ZGMn13),
- Q:What are the reasons for the spalling of refractory bricks in the production of lime kiln?
- In the course of the production of lime kiln, the local block of refractory brick is a very dangerous signal. It is suggested that you stop the kiln to prevent the collapse of a large area. Lime kiln is the main equipment for the production of limestone kiln and rotary kiln is two, with the growth of calcium carbide lime kiln industry, iron and steel industry, the construction industry to the amount of limestone has become the main production equipment, and refractory bricks became the heart of lime kiln.
- Q:The difference between aluminium refractory and magnesia refractory
- Therefore, the difference between the two is a neutral, one is alkaline, the original product is different naturally.
- Q:What should be used as binder for making high alumina bricks?
- In addition, high alumina micro powder can be used as binding agent, or high alumina micro powder and clay powder are prepared according to a certain proportion, and synthetic mullite is used as bonding agent. With these binders, high alumina bricks without two expansion can be prepared.
