On May 24th, the reporter learned from Dalian Rubber & Plastics Machinery Co., Ltd. that the first steel wire cord rolling unit independently developed in China was already under the assembly line of Great Rubber and Plastics and will be shipped to the world's 20th tire company in the world. the company. This means that China's last technology for the domestic production of key equipment for all-steel radial truck radial tires has been conquered, and China has the capability to supply complete production equipment to all steel tire production enterprises.
The unit adopts the advanced hot-rolled wireless hot-rolling method, and several hundreds of wires without latitude are used to complete double-sided stickers at a speed of 50 to 70 meters per minute under the condition of ensuring uniform spacing and tension. Glue, made of steel cord with a total thickness of 1 mm to 3.5 mm. The unit also uses integrated high-speed synchronous constant tension control, automatic product length cutting, ray inspection thickness inspection and other international advanced technologies to achieve integrated control of the machine, electricity, liquid and gas. The expert group organized by the China Petroleum and Chemical Industry Association believes that the entire unit has reached the international advanced level and filled the gaps in the domestic market. It can be put into production and promote its use.
The unit is the key equipment for the national "Tenth Five-Year Plan" major technical equipment research project - Carry-carrying radial tire equipment and engineering radial tire key equipment development project, and it is also the most expensive equipment among the key equipment for all-steel tire production. Due to its large production capacity, the annual production capacity of a set of designed tires reaches more than one million, so this unit is generally the "only son" equipment of the tire manufacturer. With the high technical content of this unit, it is difficult to develop, so user companies are very cautious about the selection of the unit. Because of this, although the unit has been developed for many years, it has not been able to achieve localization and has had to spend a lot of foreign exchange for a long time. According to incomplete statistics, since 2002, China has introduced more than 40 sets of steel wire cord rolling units, and the introduction cost exceeds 100 million US dollars.
It is understood that before this large rubber and plastics has developed and produced a steel cord roller calendering auxiliary machine for a number of domestic users, and designed and manufactured a wire/fiber dual-purpose calendering unit for the Vietnam Venus tire plant, but there is no complete set of steel wire. The curtain calender unit was formally used. Shandong Linglong Company, as the first user to “eat crabsâ€, provided guarantee for the unit to fully realize localization.
It is reported that this unit has caused great concern in the domestic tire industry during the development process. At present, the contract for the second unit has been signed and will be completed at the end of the year. In addition, there are four tire companies are negotiating orders.
