At 10:40 on June 13, with a normalized steel plate smooth baked slab line of Angang Steel Plate Mill Heat Treatment Furnace heat load test is successful, which marks the international advanced level heat The system was officially settled in Anshan Iron and Steel.
Due to aging equipment, the decline in accuracy, Angang Steel Plate Mill slab line is the original heat treatment furnace and quench unit # 1 to become the bottleneck restricting plate production capacity and quality. Face of a continued downturn in the market environment, the plant vigorously implement the strategy of differentiation through the production of high value-added products to expand profit margins. Implementation of technological innovation, as the necessary precondition to speed up the conversion of technical advantages to the product advantages of heat treatment. Last September, the heat treatment furnace and quenching machine 1 # shutdown began to transform the construction project to the introduction of heat treatment furnace of the thermal engineering company in Germany LOI.
It is understood that the sets of heat treatment systems for the protection of nitrogen, radiant tube heating roller hearth heat treatment furnace, mainly used for normalizing and tempering of steel plate, designed annual handling capacity of 170,000 tons, handle plate thickness specifications is 150mm, the entire technology at the international leading level. As a result of the oxidation with the water system of automatic control of the hardening machine, the surface quality of steel sheet, plate type, performance, have increased dramatically.
Short duration, tight funding, civil construction and in the winter, Angang Steel Plate Mill organization of construction units and design units in accordance with the actual situation of the site repeatedly refine the construction program to overcome the impact of geological water level, low winter temperature welding, three-dimensional three-dimensional cross- multi-professional jobs, and a series of production and technical problems to ensure that the duration and quality. In order to reduce the project investment, the plant optimization process design, and the transport roller shutter machine, part of the deceleration of the motor and electronic control equipment to play a role in saving the investment of tens of millions of dollars are carrying out appropriate repair. The plant also combined with the production side to side construction features, re-balance the production logistics, strengthening equipment improvements, to ensure the normal production of 2 #, 3 # heat treatment furnace, so that the production transformation correct to ensure the early realization of the heat treatment furnace # 1 heat load test.
It is reported that production of the heat treatment furnace of the # 1 Plate Mill heat production will reach 20% of the total output, effectively enhance the capacity of the heat treatment of the Anshan Iron and Steel Plate, the ability of products in the market competitiveness of Anshan Iron and Steel Plate and respond to market challenges will also be further enhanced.
