In recent years, in order to meet the requirements of various rolling systems, various product specifications, high quality products and high output, our institute has conscientiously digested and absorbed advanced technology at home and abroad, designed a set of high-speed, multi-variety and high-quality small section steel and bar cold bed equipment with the same international advanced level. The annual output of bar can reach 900,000 tons, which has reached the advanced level of similar equipment abroad.

　　(1) Product introduction

　　Our company's cold bed production line has step-by-step, chain and other products. It is divided into five parts: upper steel device, input roller, cold bed body alignment roller, lower steel device and output roller. Its input roller is driven by frequency conversion motor, and the cooling bed body is driven by double envelope worm gear reducer. It has the advantages of strong driving ability, high efficiency, strong adjustability and long service life. It can make the optimal process design according to the user's requirements.

　　(2) Major achievements

　　Our company has successively designed and manufactured more than 20 sets of cold bed production lines for domestic and foreign iron and steel enterprises such as Ma Gang, Xilin Iron and Steel Company, Baosteel Nantong Iron and Steel Company, Qingdao Iron and Steel Company, Amman, Mozambique and so on.

　　(3) Technical parameters

　　1. Cooling area: 6m-15m*40m-140 M

　　2. Linear speed of input roller: 10-20m/s

　　3. Cooling specifications: 10-60 round and threaded steel

　　In recent years, as the rolling process tends to adopt non-twist rolling, compact vertical roll mill, advanced looper, computer control and other means, the rolling speed has been rapidly improved. In this way, a new development topic is put forward for the process of the rear cold bed production line of rolling line. As the throat equipment of the cold bed, how to solve the feeding problem of the cold bed of the new high speed rolling mill is imminent. The new cold bed feeding device can meet the requirements of the modern small section steel and bar mill for the cold bed feeding device.

　　It is believed that with the development of rolling equipment in our country, the feeding device of the high-speed and multi-variety cold bed production line will be widely applied.
