Control method of slow-cooling steel wire rod loop

The invention discloses a control method of a slow-cooling steel wire rod loop, and relates to the technical field of metallurgy. The control method comprises the following steps: accelerating a clamping roller, regulating a spinning machine support plate, accelerating and proportioning a drum transportation air-cooling roller way, setting accelerated speed for the clamping roller after a materialis rolled on line and is separated from a rolling mill, thereby guaranteeing conveying ability on a rolled part; performing up-down regulation on the spinning machine support plate according to the loop size during spinning, and enabling the two sides of a drum to be dropped on the support plate during spinning; and accelerating each section of the air-cooling roller way, and enabling the drum tobe uniformly scattered on the air-cooling roller way while the drum is transported on the air-cooling roller way. The control method is easy in operation, can effectively control coiled loop qualityof the slow-cooling steel w
