In order to ensure that the surface of the pulled steel wire is clean and powder-free, a cleaning equipment device is used for cleaning treatment. An appropriate (usually 1%) metal surface treatment agent is added to tap water, and the surface of the steel wire is washed by a high-pressure submerged pump (1.1KW). At the same time, a cleaning ball is used to wipe the surface of the steel wire in the passage. In order to ensure that the surface of the steel wire is wrapped without water before entering the winding line, So, at the outlet of the steel wire, a high-pressure air blowing device is used to vigorously blow the steel wire surface 360 ° without gaps, ensuring that there is no water vapor in the steel wire during winding. This cleaning machine is divided into two layers: upper and lower, with a steel wire passage layer on top. The specification is 400X300X2000, which is made of stainless steel welded material. Inside, there are nine adjustable cone wiping devices, which tightly contact the steel wire and the cleaning ball for wiping; The lower layer is a water storage tank, with a specification of 800X700X1600, which is welded from 4mm stainless steel plate. There is a filtering area in the water tank, and the filtered water is pumped out from the anti-corrosion liquid pump on the water storage tank into the upper aisle water tank for flushing. The underwater pump will not block and has a longer lifespan. The lower water tank is equipped with a decontamination hole to remove debris and garbage. According to customer needs, in areas where the weather is too cold, an electric heating system or a steam heating system can be installed on the water tank, and the heating temperature can be designed to maintain a certain temperature for flushing and wiping with water.

According to the Science Times, Baosteel's preliminary rolling mill is a complete set imported from abroad and is one of the largest mills in the world. The pressing nut is an important part of the rolling mill pressing device. The nut weighs 2340 kg and is made of copper alloy material, mainly composed of screw and silk.
The function is to reduce the rolling force by the high-speed rotation between the screw and the nut, and the rolling force of up to 2000 tons is generated. Therefore, the pressing nut is different from the conventional rolling pressing nut, and the material is required to satisfy the heavy load. It has good strength, high wear resistance, high temperature resistance, seizure resistance, and better hardness matching performance. In addition, the replacement of the nut is carried out at the same time as the initial rolling mill shutdown, so the service life is required to be at least 6 years. .
In view of the strict requirements on the performance and service life of the pressed nut, and the fact that there are no manufacturers producing such products in China, Baosteel has been imported from abroad and is expensive. The two-way and Baosteel agreed to jointly conduct research on the localization of the product.
Researchers have researched and researched process parameters for more than a year, and developed a new material copper alloy with high wear resistance and anti-adhesive wear similar to tin bronze. Using this new material through special casting method and heat treatment process, Double has succeeded in manufacturing a pair of pressing nuts for Baosteel, and its performance indexes meet the requirements put forward by Baosteel.
Successfully developed the largest rolling mill nut in China
At present, the crushing nut used in China's largest Baosteel roughing mill has been successfully developed in China's second heavy machinery group (double), and the “localization†of this product has taken a critical step.
