Embodiment 1

[0026] A method for improving the high wire yield of rods, comprising the following steps:

[0027] 1) Improve the finished product rate by controlling the heating zone. The heating temperature is controlled at 1000°C, and the holding time after warming is 4 hours. The temperature at the beginning of heating in the heating furnace is 1100°C. 850℃, strictly implement the heating system, improve the heating efficiency, promote the uniform heating temperature of the billet, avoid black marks, reduce oxidation and burning loss, maintain normal furnace conditions, reduce the maintenance difficulty of the heating furnace bottom, and ensure smooth production;

[0028] 2) Adjust the roll gap of the finishing mill to reduce the occurrence of rolling scrap. It is necessary to ensure the accuracy of the roll gap of the finishing mill and the uniformity of each shift, to ensure that the head of the rolled piece in the finishing mill bites smoothly and the strip rolling state is good , the...

Abstract

The invention relates to the technical field of high-speed bar yield improvement, and discloses a high-speed bar yield improvement method. The method comprises the following steps that (1) the yield is improved by controlling a heating zone with the heating temperature controlled at 1,000-1,400 DEG C to be preserved for 4-7 hours, the start heating temperature in a heating furnace is 1,100 DEG C,and the temperature in the heating furnace is controlled higher than or equal to 850 DEG C after the heating is finished; a heating system is strictly executed, and the heating efficiency is improved,so that the billet heating temperature is promoted to be uniform, black marks do not appear, the oxidation burning loss is reduced, the furnace condition is kept normal, the maintenance difficulty ofthe bottom of the heating furnace is reduced, and the production is guaranteed to be smooth. According to the method, less finished scale is generated due to good guide groove air nozzles of water tanks, good water nozzle gaps, correct maintenance and water pressure increase of the water tanks, the yield of high-speed bars is integrally improved from multiple aspects, therefore, it is convenientfor an enterprise to implement the method effectively and efficiently, the implementation efficiency and the yield of the high-speed bars are improved, and the method is convenient to apply.

Description

technical field [0001] The invention relates to the technical field of improving the high wire yield of rods, in particular to a method for improving the high wire yield of rods. Background technique [0002] Bars generally refer to a material product whose cross-sectional shape is circular, square, hexagonal and octagonal, etc., and whose length is relatively large relative to the cross-sectional size, and is usually provided in straight strips. Bars are generally It can be machined, and there are many materials that can be made into rods, such as steel rods, aluminum rods, copper rods, wooden rods, rubber rods, plastic rods and glass rods. [0003] The high or low yield of high-end bars directly affects the production cost of the enterprise. From billet to steel, not only the appearance changes, but also various data indicators of the operating cost of the enterprise, which measure the process technology of the rolling mill. The level and the finished product rate also di...
