Production process of cold drawn 304 100 diameter stainless steel round bar

The cold drawn 304 100 diameter stainless steel round bar manufacturer's production line production process: steel engineering acceptance → heating → rolling → double-length cutting → refrigeration → cutting → testing → packaging → measurement verification → warehousing.

Small and medium-sized bars are manufactured by stainless steel bar suppliers. The specific categories of small and medium-sized rolling mills are divided into: continuous, semi-continuous and horizontal. At present, fully continuous small and medium-sized rolling mills are mostly used. The popular construction steel bar rolling mills nowadays include universal fast-rolling construction steel bar rolling mills and 4-cut steel bar rolling mills. The commonly used billets for continuous small and medium-sized rolling mills are generally small steel billets. The circumference is generally 130~160mm, and there are also 180mm×180mm. The length is generally 6~12 meters long, and the unit weight of the billet is 1.5~3 tons. The rolling lines often have a flat-vertical alternating layout to achieve distortion-free rolling. The size of the sound card rack is determined based on the standard of rolling a sound card rack together. Rolling mills are often composed of even numbers of passes. According to different billet specifications and finished product specifications, there are 18, 20, 22 and 24 small and medium-sized rolling mills, with 18 being the most popular. Adjustable speed, shrinkage force and unsupported rolling are the characteristics of modern fully continuous small and medium-sized rolling mills.

304l stainless steel rod rolling is an easy type of plate rolling, and it can be done in a variety of ways. From the three-roller horizontal type, to the twisted double type, from the semi-continuous type to the fully continuous type, bars can be produced, but their production volume, specification accuracy, success rate, and compliance rate are all very different. The bending stiffness of the three-roll mill is low, and changes in heating environment temperature will cause significant fluctuations in product specifications. In addition, the horizontal speed is relatively slow and the rolling time is long, resulting in an increase in the temperature difference between the head and tail of the slab, making it easy for the specifications to change. , and the characteristics are uneven, the production volume is very low, and the quality fluctuates greatly.

Compared with hot rolling of 16 manganese steel, the rolling process of stainless steel bars is mainly reflected in the inspection and cleaning of ingots, heating methods, hot-rolled strip hole design, rolling temperature control and product line heat treatment processes.
