Problems solved by technology

[0004] However, due to the limitations of traditional hot rolling and thin-slab continuous casting and rolling processes represented by CSP in terms of production specifications, "substituting hot for cold" cannot achieve further development. Although ESP and other production lines can produce thin-gauge strip steel, but Because of its thinner specifications, when rolling at low temperature, the temperature and heat history of the strip is relatively low, and the strength is relatively high, which affects the customer's deep processing

Abstract

The invention provides a temperature control system and method for hot-rolled thin strip steel production. The temperature control system comprises a hot-rolled thin strip steel production line, and rollers, a width and thickness gauge and a stream cooling device are sequentially arranged in the hot-rolled thin strip steel production line in the rolling direction of strip steel; the temperature control system further comprises a heat preservation heating unit, a first temperature sensing unit, a second temperature sensing unit and a control unit; the first temperature sensing unit is arranged at the outlet ends of the rollers, the heat preservation heating unit is arranged between the first temperature sensing unit and the stream cooling device, and the second temperature sensing unit is arranged at the outlet end of the heat preservation heating unit; and the control unit is connected with the heat preservation heating unit, the first temperature sensing unit and the second temperature sensing unit. According to the temperature control system and method for hot-rolled thin strip steel production, the temperature during low-temperature strip steel production can be effectively increased, and the requirement of customers for the strip steel forming quality is further met.

Description

technical field [0001] The invention relates to the technical field of temperature control for strip steel production, and more specifically relates to a temperature control system and method for hot-rolled thin strip steel production. Background technique [0002] my country is a big country of steel production, and strip steel has always been the most widely used steel product with the highest technical content and the highest industrial added value. With the development of the economy, the production of strip steel has been showing a growing trend. [0003] At present, in order to cope with the competition in the market, steel production enterprises have put forward the high starting point development goals of process modernization, large-scale equipment, production intensification, resource and energy recycling, energy consumption minimization, and economic benefit optimization, and actively promote the steel industry. Energy conservation and emission reduction and tech...
