Aluminium Oxide For Blasting Manufacturers Italy

It should also be pointed out that the so-called two-step calcination process is to calcine the concentrate in a high-temperature kiln after light burning, re crushing and ball pressing(brown aluminium oxide). The process is widely used at home and abroad because it can activate the crystal lattice of raw materials, reduce the sintering temperature, increase the density of clinker and facilitate the artificial synthesis(aluminium oxide abrasive grit). High pressure forming is an important means to obtain high density of products.

The technology of extracting magnesium from seawater is an effective way to produce high-purity magnesia(aluminium oxide blasting grit). Western European countries use more hydraulic presses, generally the most commonly used pressure is 1500-2000 tons; the maximum I force of lever press and hydraulic lever press is 1300 tons, and the United States uses more; Japan, the Soviet Union and China mainly use friction press(70 grit aluminum oxide blast media). The largest one is 1250 tons, Japan 630 tons and China 800 tons.

In addition, since the 1970s, some countries have also adopted isostatic pressure forming machines (also known as hydrostatic presses), which can be divided into wet and dry forming methods(100 grit aluminum oxide media). The former is low productivity and suitable for products with many varieties and small batches, while the latter is suitable for products with large batches(240 grit aluminum oxide). In the 1970s, the automation level of foreign fire fighting material factories has also been greatly improved.

At present, the submerged nozzle brick and long plug brick for continuous ingot casting abroad are generally formed by hydrostatic press(brown fused alumina). In the aspect of test technology, there are 1700 ~ 2000 ~ C tunnel passengers in foreign countries(46 grit aluminum oxide). The way to raise the kiln temperature is to use high calorific value fuel such as heavy oil or natural gas, to use double-layer kiln top, to strengthen the preheating temperature of primary air and oxygen enriched blast, etc.

At the same time, the high-temperature tunnel is developing towards the direction of top burning or both top burning and side burning(fine grit aluminum oxide). Its characteristics are: the combustion is carried out in the space of brick stack, which causes less damage to the kiln wall and reduces the heat loss(aluminum oxide abrasive media). The basic bricks can be divided into two types: fused magnesia chrome bricks and fused magnesia bricks. There are many types of high-pressure brick presses abroad, the largest of which is 8000 tons.

At the same time, the temperature difference between the top and bottom of the dense chamber is small(brown aluminum oxide), the calcination quality of the products is good, and the thermal efficiency of the kiln is high. A high temperature tunnel with burners installed on the top and side walls of the kiln was built in Britain in 1977, with a service temperature of 1750c(aluminum oxide abrasive blasting grit). High temperature firing is the key to produce high quality refractory products.

From batching, mixing to molding, drying and firing, the production is controlled by electronic computer devices(180 grit aluminum oxide). Through the research of basic theory and damage mechanism, we can improve the product quality, create new varieties, and extend the service life of the furnace(180 grit aluminum oxide blasting media). According to the data, in recent works, Japan's more advanced Pinchuan refractory company has 159 five brick presses, including 101 friction presses.
