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: What are the requirements for Rubble backfill height?: 1, filling thickness is not greater than 50cm.2, filling, the use of layered filling.

Q: What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?: All the raw materials adding order, mixing time, material and material moisture trapped. 4, the pressure and the volume density of Pei brick and brick Pei size etc..

Q: What's the difference between a well type annealing furnace and a box type annealing furnace?: 1. The shell of the furnace is welded by section steel and steel plate. 2, the furnace cover support adopts steel and guide rail combination mobile type. 3. The heating element is made of high resistance alloy 0Cr25Al5 produced by Beijing Shougang Group and arranged on the furnace side. 4, because the bottom bearing adopts high aluminum bricks, the circle center of the furnace set small, inside and outside heating. 5 、 furnace cover adopts hydraulic lifting, motor control, automatic walking. 6 、 temperature control system adopts PID SCR control, high accuracy.

Q: What are ordinary bricks, refractory bricks, hollow bricks?: Light yellow or brownish. The utility model is mainly used for laying smelting furnaces, and can withstand high temperature between 1580 DEG C and 1770 DEG C. Also called brick. Refractory material of a certain shape and size. According to the preparation process can be divided into bricks, brick, electric melting brick (Rong Zhuzhuan), the refractory insulating bricks; according to the shape and size can be divided into standard brick, brick, brick and other specific type. It can be used as high temperature building materials and structural materials for construction kilns and various thermal equipments, and can undergo various physical, chemical and mechanical changes at high temperature. For example, refractory clay brick, high alumina brick, brick, brick etc..

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: How to distinguish the good or bad of the high aluminum brick?: Weigh the weight of the next block. According to the weight standard, a high alumina brick is 3.9 kg in weight, two in high alumina brick, three in high aluminium brick and 4.5 kg in 4.2. The same grade, the same type of high alumina brick, if the weight of a single brick to this standard, but for high quality high alumina brick, otherwise, can not reach such a weight, it shows good quality. If there is a crack, a large piece of broken angle, four sides of inequality, it is for substandard products.

Q: What kind of material is the general metal case?: Generally speaking, the outer surface of the case is usually made of a steel plate of more than 1 millimeters. The thickness and the material of the steel plate are directly related to the rigidity of the case, as well as the capability of sound insulation and anti electromagnetic radiation. The regular manufacturers of the chassis plate thickness not less than 1.3mm, but there are also some small manufacturers with a thickness of only about 1mm steel, we do not need the ruler to the amount, as long as you put him up, the more weight in the same volume of the chassis is better, in addition, we can also use the finger bomb case shell. If you can hear the crisp percussion sound proof of the casing plate is thin and brittle, if you hear is relatively dull and heavy sound that the chassis material must be good, good general steel plate coated with a layer of thin zinc (bright part), so it can withstand high strength, impact resistance, hardness high elasticity. The frame parts of the chassis are made of high quality materials with high hardness. They are bent into angle shapes or strip shapes. We can shake the chassis frame of the case by hand. Good chassis should be relatively stable, and inferior chassis light is easy to shake. When choosing, we should also pay attention to the outer edge of the case and the edge of the inner bracket. Whether the incision is smooth or not, a good case will not appear in the case of rough edges, sharp edges, burrs and so on. While the poor case appears above phenomenon, often appear when installing the blood splattered". Generally speaking, the chassis must go through the corresponding grinding process before leaving the factory. The edge of the flat plate some burr, edges and corners are rounded, the corresponding fold some corner. When you install such a case, you don't worry about cuts, and some rough, poorly built cabinets tend to scratch your hands.

Q: What is the difference between metal compounds and metal solid solutions?: Sigma phase belongs to Affirmative system, there are 30 atoms in the unit cell, two element alloy, sigma phase formation is related with the following conditions: (1) the atomic size difference, phase difference between the maximum sigma atomic radius of a tungsten cobalt, the atomic radius difference is 12%. (2) there is a set of cubic lattice elements (coordination number 8), and another component is face centered cubic or dense six square lattice (coordination number is 12). (3) appear in "average number of races" (s+d layer electron number) in the range of 5.7 ~ 7.5. The region of the presence of sigma in the two - element alloy is shown in table 3. In the three element system, the concentration and temperature range of the formation of the sigma phase are affected by the addition of third components. Usually in chromium stainless steel in Fe Cr phase, in Fe - Cr - Mn three yuan, sigma phase iron chromium and chromium can form Mn two element, when the addition of manganese in stainless steel, will promote the formation of sigma phase, and stabilizes the wide temperature range. Many of the Fe Cr alloy elements. The phase temperature range increases. In less than 820C stable Fe Cr phase, silicon promotes the formation of D phase and the stable temperature increased to 900 to 960 DEG C, manganese and molybdenum can improve the temperature stability of sigma phase to 1000 DEG C.

Q: The difference between clay bricks and clay bricks: Sintering bricks do not have clay bricks, so sintering bricks are made of stone. Clay brick is clay cooking, two yo, qualitative difference, but the appearance and color almost, but the quality is very different, life expectancy is also a great gap.
