Daye Nonferrous Refinery Steam Selenium Sand Roasting Technical Improvement Domestically Advanced Level

On April 8th, Daye Nonferrous Company's rare and precious plant successfully reformed the selenium rotary kiln burner. After the transformation, this technology has reached the advanced level of similar domestic enterprises.
Steamed selenium sand roasting is the first important process for the production of gold and silver products. This process plays an important role in improving the quality and output of gold and silver products, reducing production costs, and improving production efficiency. In order to ensure the quality of silver (silver products have reached international standards) and further increase the production of gold and silver, the plant's technology department aims at burning selenium-burning kiln burners: the burner type is too small, the natural gas is not fully burned, the temperature zone is easy to turn off, and the flame is turned off and then reignited. Difficulty, technical problems such as low life cycle of the burner core components were studied, and through repeated comparison of various burner data used by peer manufacturers, three Italian TBG-55P type combustion engines were finally selected. After the combustion engine was put into use The combustion of natural gas is sufficient, the CO2 content in the flue gas is ≤0.1%, and the ignition is convenient, the temperature control is stable, and the technical requirements of the process to the temperature are met. Not only can the life of the rotary kiln be extended, but only natural gas consumption can save costs of 278,600 yuan.

Engine Oil

Engine oil, that is, the engine lubricating oil,is equivalent to the blood of a car. The Motor oil consists of two parts: basic oil and additive.


SAE lubricating oil viscosity classification for winter oil grades are: 0W, 5W, 10W, 15W, 20W, 25W, the symbol W represents winter, the smaller the number before W, the lower the low temperature viscosity, the better the low temperature fluidity, suitable for the lower the minimum temperature;

The summer oil grades of SAE lubricating oil viscosity classification are: 20, 30, 40, 50. The larger the number, the greater the viscosity and the higher the applicable maximum temperature;

Car Engine Oil Feature:

1.It is premium synthetic engine oil,provides super protection during engine starting,especially under extremely cold weather.
2.Excellent cleaning ability,maintain good abrasion resistance.
3.It uses super synthetic base oil,can procide longer lubrication under low temperature.
4.Uses high performance imported additives,can prolong life of engine oil.
5.Maintains stability and good performance of oil film.
