For example; the bearing box has large wear and deformation, and the outer ring of the bearing is mostly broken.本都跣.銮客馊η慷龋灰源锏街岢惺倜畛.

ㄋ ( (16) 岢 core take (15) 蜗都芭浜 1, bearing accuracy: mainly based on the bearing component requirements for the rotation accuracy and the bearing life requirements to determine the bearing accuracy grade. Rolling mill bearing accuracy grade improved; although the bearing A single set of cost improvements; but brings the following strengths:
.1), the internal stress reduction of the bearing parts; the stability of the bearing parts; the reduction of the crack elements of the parts;
.2), the roughness level of the bearing work surface has improved (rough peak reduction. 谥岢腥蠡湍さ欣谥岢腥蠡湍さ男捎氡, ぃ皇怪岢衅@倜倜灾岣.
.3), the roughness level of the bearing cooperation surface is improved; the bearing cooperation is more secure; the cooperation is prevented from "crawling"; the bearing life is improved.
.4), better speed; reduce bearing heat; good for bearing life.
.5), inductive bearing cost reduction; mill operating rate progress.
2, bearing clearance: bearing normal operation bearing clearance is an important technical parameter, it directly affects the bearing load distribution, friction, temperature rise, service life, etc.. Due to the poor working conditions of the rolling mill bearing; It is necessary to consider its rolling load, rotational speed, smoothness, temperature rise, cooperative interference, rotation accuracy, etc.; the principle is that under the condition of working condition; the smaller the bearing clearance, the better the service life of the rolling mill bearing. Under the condition, the rolling mill adopts the C3 or C4 group standard clearance; in the operation process of the rolling bearing; the bearing clearance can be judged according to the condition of the bearing damage.
.1), bearing burned; if it is not due to "roller climbing", the associated parts are poor and the smoothness of the bearing causes overheating of the bearing; then it can be considered that the bearing clearance of the rolling mill is too small,
.2), bearing ring and roller fragmentation; if it is not the original data, bearing quality, excessive impact load and poor installation; can be thought that the rolling mill bearing operation is too large; the bearing load wrap angle.硐敫汉砂怯 κ120 ° ~ 150 °); the formation of data per unit area strain pressure; roller load caused by large.

Organic raw materials
Organic raw materials that are oil and natural gas as raw materials of petrochemical, food fermentation alcohol or solvent industry, coal gasification of raw materials and dry distillation of coal tar prepared or fractionated from a variety of organic chemical products industry. In China's organic chemical industry first coal-fired calcium carbide route, coal gasification of methanol, formaldehyde route and recovery of coal tar benzene, naphthalene, anthracene and other routes and food as Raw Material fermentation distillation system developed alcohol.

Basic organic chemicals used in the main raw materials are: hydrogen, carbon monoxide, aliphatic hydrocarbons (methane, ethylene, acetylene, propylene, C4 above the aliphatic hydrocarbons), aromatic hydrocarbons (benzene, toluene, xylene, ethylbenzene) and so on. From the crude oil, petroleum fractions or low-alkane pyrolysis gas, refinery gas and gas, after separation treatment, can be made for different purposes of the aliphatic hydrocarbon feedstock; from the catalytic reforming of the reformed gasoline, hydrocarbon cracking pyrolysis gasoline As well as coal dry distillation of coal tar, can be separated from the aromatic feedstock; the appropriate petroleum fractions can also be used directly as raw materials for certain products; from the wet natural gas can be separated from methane other than the lower alkanes; from coal gasification and natural gas, refining The conversion or partial oxidation of the plant gas, the petroleum fraction or the crude oil can be made into syngas; the calcined calcium carbide, or the natural gas or naphtha, can be used to produce acetylene. In addition, raw materials can be obtained from agricultural and sideline products.

Organic raw materials products are widely used, can be divided into three aspects: First, the production of polymer products for the raw materials, that is, polymerization of monomers; Second, for other organic chemical industry, including fine chemical products, raw materials; For solvents, refrigerants, antifreeze, gas adsorbents and so on. Basic organic chemical industry is the basis for the development of various organic chemical products, is the main component of modern industrial structure.
