How is the castable development prospect?

For some want to do industry castable but very hesitant people, who are considering how is industry castable prospects, technical staff of Xinmi Changxin today to give you an answer.

In fact, choose industry castable shows that you are still very eyes, because the development prospect of the castable is very broad, whether can use castable in what place, so it can be said is the choice of castable is not wrong; there is the prospect of castable is good but also because of their condition outstanding, first of all the first is the castable high-temperature considerable, so whatever is great in the iron and steel factory or in the furnace of the demand, and the use of many places, development benefit will be relatively good many; and then pouring material and long service life, unlike the ordinary refractorymaterial, we did not take long for the index has declined step by step, to bring certain influence to our production and work efficiency, problems like this we can choose castable. But like the petrochemical industry are large enterprises to use castable, the future development has brought great benefits, so in general the development prospects of castables or very good.

The content of the development prospects of castable refractory maybe you have some understanding of it, if you want to ask more about castable knowledge can consult us freely.

Experts explain – clay firebrick compliance requirements

The experts tell you fireclay brick compliance requirements. Acceptance of fireclay bricks masonry of refractory brick works, to carefully check the flue, furnace, special attention should be paid to the vault, is the single arch, the bottom of the equipment. The next writer will give you detailed introduce:

1, in the masonry firebrick, refractory material used and the mud, according to the level and composition of label, shall be in accordance with specifications and drawings;

2, to ensure the quality of masonry of refractory clay brick is good, also is to follow the wrong sewing, levelness and verticality, mortar joint thickness and standard, size and drawings in accordance with;

3, in the process of acceptance of the furnace body, assign out for shop assistant director must personally from top to bottom, according to each part of the furnace body check, are several mortar joint thickness inspection, furnace body parts when measured by acceptance necessary enrollment size, careful examination of many important structure of the furnace body the building.

The above is writer introduce you acceptance fire brick requirements, for reference purposes only, hope to help you, if you have what doubt, please feel free to contact us!

Notes on using anhydrous stemming

The anhydrous stemming mainly used in tadpole, but out of the mouth of the clay gun susceptible to iron slag erosion and chemical erosion, caused by the slag iron out not only, but also prone to iron mouth fracture, leading to iron out the tadpole accident. So we in the use of anhydrous stemming must pay attention to:

1, pay attention to insulation. The general insulation at 20-60 degrees Celsius advisable, winter use the gun mud roasted in the fire soft use beside the gun can be used, after baking gun measures 2, do not mix with water use, not to install mud gun water, performance or lost anhydrous stemming.

3, to change the mud to bore in the clean water stemming, clay loading quantity according to the requirements of the iron mouth, usually with water stemming amount of 1/5 or 1/4, that is 80-120 kg.

4, open iron, iron mouth eye size should be appropriate, to ensure that the tapping time, generally for diameter should be 60-80 mm.

5, plugging tadpole, don’t immediately returned gun, 10-20 minutes back gun, in order to prevent iron mouth blown open.

6, the use of water stemming, manufacturers can also be treated according to its own characteristics, in order to maintain taphole, ensure safety in production.

Anhydrous stemming and its main characteristics

Anhydrous stemming is to continuously improve the production of pig iron (especially after burning), with the traditional water stemming tadpole maintenance is not good situation, after repeated testing and improvement, a new type of refractory material is developed, which adapts some advanced refractory materials and chemical raw materials, with advanced and a unique process preparation, its advanced technology, excellent quality, less consumption, there is a water gun mud can not be comparable, the blast furnace iron mouth maintenance, flow stability, promote the safe production, plays a role is the key to reduce the accident potential.

The main characteristics of anhydrous stemming:

Compared with the traditional water gun mud, has the following advantages using anhydrous stemming:

1, less dosage, high strength. Anhydrous stemming each time only needs to install the 80-120kg, as the water gun mud made of new refractory materials, especially high strength, with clay content can be less ensuring tadpole depth; high temperature resistance, anti slag erosion, non stick iron slag, iron mouth without baking, is another characteristic of anhydrous stemming, from the tadpole maintenance is very convenient.

2, flow stability, an accident is not easy. The anhydrous stemming high strength, using drilling drilled iron mouth aperture always remains the same size; ensure the hot metal flow uniformity, reduce or avoid running large flow, diffuse iron slag, explosion accident occurred. At the same time, can greatly reduce the labor intensity of workers.

3, ensure net iron slag, promoting the furnace, using anhydrous stemming generally, aperture iron mouth than the use of water stemming from aperture small, under the same pressure, anhydrous stemming, can fully guarantee the blast furnace slag and iron out net, the hearth, active space, and promote the furnace operation, and is conducive to strengthening smelting, improve the management of the production of pig iron.
