Device for on-line detection of die casting argon protection effect and detection method

Abstract

The invention provides a device for on-line detection of a die casting argon protection effect and a detection method. The device comprises a sampling pipe, a cooling device, a dehumidifying device, an adjusting valve, an air extracting pump and a tail gas pipe which are sequentially connected in series through pipelines; a first dust filter is arranged between the sampling pipe and the cooling device; an instrument is further arranged between the dehumidifying device and the air extracting pump; and the instrument and the adjusting valve are connected in parallel. The detection method includes the steps that before die casting pouring, the sampling pipe and a sample taking pipe of an argon protecting cover are communicated, a selection valve is opened, and the adjusting valve is closed; apower source is started, and argon in the argon protecting cover is discharged out of the tail gas pipe sequentially through the sampling pipe, the first dust filter, the cooling device, the dehumidifying device, the instrument and the air extracting pump; and oxygen content data in the argon protecting cover are displayed on the instrument. The device has the beneficial effects that the device is novel in structure and easy to manufacture, and the automation level of field operation is improved.

Description

technical field [0001] The present invention relates to an auxiliary equipment for mold casting operations in the iron and steel metallurgy industry, in particular to a device for monitoring the effect of argon protection pouring and its use method used in die casting during argon protection pouring operations. The device mainly It is used to monitor the oxygen content in the argon protective cover in real time, and display the corresponding data monitoring results in real time, instructing the on-site operators to do a good job of argon protective pouring operation, so as to prevent the secondary oxidation and other quality of the molten steel during the pouring process question. Background technique [0002] At present, the special steel industry at home and abroad has many argon protection pouring methods in the die casting process, but there is no monitoring device and system for monitoring the effect of argon protection pouring. Therefore, during the argon protection po...

Problems solved by technology

[0002] At present, the special steel industry at home and abroad has many argon-protected pouring methods in the mold casting process, but there is no monitoring device and system for monitoring the effect of argon-protected pouring. Therefore, during the argon-protected pouring operation, the operator can only Before starting the pouring, the argon gas should be turned on and kept in a large flow range to work. If other abnormal conditions occur during the pouring process, the argon gas protection pouring effect cannot achieve the expected effect, and the on-site operators cannot judge the argon gas protection pouring effect. If the argon protection pouring effect is not good, it will directly cause quality problems such as secondary oxidation of molten steel
