On September 19, 2009, the company held a technical consultant appointment ceremony in the conference room of the technology center, and officially hired Professor Novodin from the Czech National Glass Research Institute as the technical consultant of Yantai Thermal Equipment Co., Ltd. Hao Tingbin, chairman of the company, Zhuo Zhengzong, chairman of Jesse General Motors, and relevant leaders and technical personnel of the technology center attended the appointment ceremony.
In order to further improve the quality and grade of the company's equipment and better base itself on the world market, on July 19, 2008, the company signed a technical cooperation agreement with the French EFR company.
On April 18, 2009, Yantai JCL ENGINEERING CO., LTD., a joint venture established by Yantai Thermal Equipment Co., Ltd. and Singapore JCL Company, was grandly opened. Leaders of China Daily Glass Association, relevant leaders of Yantai Municipal Government and dozens of domestic and foreign experts in the daily glass industry attended the opening ceremony. The business scope of Jessie General Equipment Co., Ltd. is the design, production, processing and sales of advanced glass annealing furnaces, flower roasting furnaces, tempering furnaces and ventilation equipment. Mr. Zhuo Zhengzong, general manager of JCL company, said in an interview with reporters that the reason for choosing Yantai to invest in the construction of the factory is because Yantai is the main production area of glass equipment. 70%-80% of China's exported glass equipment is exported from Yantai. Here It is close to the port and has convenient transportation. At the same time, many supporting machinery manufacturers can cooperate with them in production, so the company has a huge space for development. Singapore JCL Engineering Pte Ltd. was established in 1952 and has a history of 56 years. It is the largest glass mold production company in Asia. JCL has established branches in many countries in the world and enjoys a high reputation.
After about 40 years of development and the efforts of several generations, China's glass industry has not only continued to develop and innovate in technology, but also made revolutionary breakthroughs in the field of related glass machinery manufacturing. However, as an energy-related industry, the industry attribute of the glass industry determines that we not only need to consider the product itself, but also need to meet China's current social needs for energy conservation and emission reduction. This is also the current direction of glass deep processing enterprises. Sustainable development is a people-oriented high-quality development and a coordinated development of economy, society and environment. Improving the ability of low-carbon transformation and accelerating the promotion of green and low-carbon development is an inevitable choice for high-quality and sustainable development. As an important deep-processing equipment in the field of glass deep-processing, glass tempering furnace has always attracted everyone's attention. How to make tempering equipment more efficient and energy-saving has become the focus of research and development of every tempering furnace manufacturer.
1. The layout of the tempering equipment is quite different from the conventional tempering equipment, which is L-shaped.
In order to clear the better stress in the glass, the glass must be heated to a temperature lower than the glass transition temperature Tg for thermal soaking, so as to clear the temperature gradient of each part of the glass and relax the stress. The selected thermal soaking temperature It is called the annealing temperature of the glass. At the annealing temperature, the glass will not have measurable deformation due to its high viscosity. The better high annealing temperature of the glass means that 95% of the stress can be removed after 3 minutes at this temperature. Also known as annealing upper limit temperature; better low annealing temperature means that only 5% of the stress can be removed after 3min at this temperature, and this temperature is also called annealing lower limit temperature. The better high annealing temperature and the better low annealing temperature are annealing temperature range.
The mesh belt type hot air circulation tempering furnace is suitable for tempering and heat treatment of various small industrial parts.
During operation, in order to keep the inner cover at a certain pressure, that is, higher than normal pressure, the pressure in the furnace is automatically controlled. If the furnace pressure falls below a safety threshold, the automatic valve (normally open) on the nitrogen line opens and the valve on the discharge line closes. The pressure of the working load space will rise with the influx of nitrogen, and the flow and pressure of the protective atmosphere will be checked and controlled. Pressure control is controlled by a pressure switch and a control relay that disconnects the outlet valve.
The annealing furnace treatment will soften the steel, while the quenching treatment will make the steel hard. In contrast, if the "normalization" treatment is applied, a layered wave iron structure can be obtained, which can effectively improve the machinability and Wear resistance, at the same time, it has the advantages of no cracks, less deformation and convenient operation. However, normalization treatment is a difficult heat treatment technology because it adopts air cooling, which will be affected by many factors. Also affects the cooling rate. Therefore, normalization uses various methods to maintain uniformity, which can be shading, enclosures, potholes, fans, etc.
2009.10.21 The glassware 2009 annual work exchange meeting held by China Daily Glass Association was held in Foshan City, Guangdong Province. Hao Tingbin, chairman of the company, attended the meeting and made a special report. The report describes the company's sales performance within one year, as well as the results achieved in the development of new products, and introduces the relevant knowledge of glass tempering furnaces.
