Improving the output of hot rolling production line.
Recent produced by continuous cold forming of sheet metal obtained by hot rolling.
Can be hot rolling method is very difficult to get the very thin strip(thin up to 0.001mm);
In the case where the slab heating temperature in hot rolling a slab is lower than 1000° C.
Precision steel tubing is a kind of high precision steel pipe material after cold drawing or hot rolling.
Hot rolling is a metalworking process that occurs above the re-rystalization temperature of the material.
The surface finished by heat treatment and pickling orprocesses corresponding there to after hot rolling.
To obtain a cladding layer with a thickness of up to 2.5 mm, hot rolling with heating up to 450° C is used.
Two kinds of hot rolling and cold rolling are classified according to the organization characteristics of the steel.
Thus, the most readily available andinexpensive products are obtained by hot rolling, profile and profile products, sheet materials.
Many steels are sold under hot rolling conditions, and rolling conditions have a large impact on impact properties.
If the service life of side guide is increased from 1 day to 5 days,the production time of the hot rolling production line may be increased by 8 hours every month.
Taking the 1780 hot rolling production line as an example, at least 1,000 tons of hot-rolled sheets may be increased per year.
The wear loss of the side guide made of conventional carbon steel is 10-15mm a day, which results in replacement andrepair of the side guide of the hot rolling unit every day.
The product has been processed by hot rolling, cold rolling or cold drawing, and currently has an important position in the domestic steel pipe industry.
The groove depth of long-life side guide decreases after wear, reducing the damage to the hot rolling strip andimprove the quality of the hot rolling strip product.
There fore, the hot rolling finish temperature maybe defined to be a suitable temperature in consideration of the necessary base metal toughness and the rolling efficiency.
The so-called 304 stainless steel black circle or 304 stainless steel rod(black stick), refers to the surface black thick,direct hot rolling, forging or annealing process, do not deal with the surface of the oxide layer of the round bar.
According to the two kinds of hot rolling and cold rolling, according to the microstructure characteristics of the steel grades, it is divided into 5 categories: austenitic body, austenite-ferritic body, ferrite body, martensite shape.
To obtain a high base metal toughness in the hot rolling process, the hot rolling finish temperature is preferably lower, but on the contrary, the rolling efficiency may lower.
When the hot rolling mill is in operation, friction between hot rolling strip at high temperature and high speed and roll, and the cooling roll surface is subjected to repeated erosion and cooling of the circulating water.
The side guide is also called guide,which is an important part of the hot rolling production line and is used to ensure the stability and directionality of the hot-rolled strip during traveling(especially before coiling), generally, there is a group or many groups of side guides.
During operation of the hot rolling unit, the high-temperature and high-speed hot-rolled sheet contacts and rubs with the side guide, which results in are serious wear of the contact part and cause such quality problems as burrs and scratch on the edge of the hot-rolled sheet.
