Problems solved by technology

[0003] Due to the low creep rate and poor comprehensive performance of traditional vermicular cast iron, its popularization and application are seriously hindered.
Although a lot of work has been done on vermicular cast iron at home and abroad, and many achievements have been made, many difficulties have been encountered in the process of popularizing and applying this material in industry, mainly manifested in the instability of vermicular treatment and the instability of vermicular treatment during the preparation of the material. The conversion rate is low and difficult to control, and the overall performance is poor
[0004] At present, most of the general cast iron relies on manual operation. The temperature, time and dosage of materials are manually operated. However, these data need to be strictly controlled. If there is a slight discrepancy, it may cause the preparation of vermicular graphite cast iron. The quality and parameters are different, and there are a lot of data that need to be measured during the preparation process. Manual memory and operation are easy to make mistakes. Moreover, due to the time-consuming manual operation, the preparation efficiency is not high due to various reasons.

Abstract

The invention discloses an intelligent preparation system and a method of low tin silicon molybdenum vermicular graphite cast iron. The system comprises a heating module, a decarburization modue, a stirring module, a component inspection module, a prompt module, a baking module, a valve control module, a PLC and an induction module; the induction module induces if the putting weight of raw materials reaches a preset value; the component inspection module detects the contents of all components of molten iron; and the PLC controls the heating module, the decarburization module, the stirring module, the prompt module, the baking module and the valve control module to perform related operations according to received data information after internal calculation and analysis. The system and the method can strictly control such various parameters as temperature, time and material putting quantity in the preparation process, reduce the error rate, improve the preparation efficiency and the quality of the low tin silicon molybdenum vermicular graphite cast iron, largely reduce the work of operators, and realize high automation of the preparation process.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to an intelligent preparation system and method for low-tin-silicon-molybdenum vermicular graphite cast iron. Background technique [0002] Modern diesel engines have the characteristics of high power per liter, compact structure, complex casting shapes, large heat loads, and high degrees of reinforcement. New updates have been made not only to the design technology, but also to the materials and manufacturing technologies of critical parts such as the diesel engine body and cylinder head. High requirements require that materials not only have high room temperature and high temperature mechanical properties, excellent thermal conductivity and shock absorption properties, and excellent thermal fatigue properties, but also require high compactness, uniformity, and reliability. The shapes of graphite in cast iron are flake, worm and spherical. Vermicular graphite is an intermediate for...
