Problems solved by technology

With the development of domestic semi-solid technology, more people in China are researching and producing semi-solid technology; at present, domestic semi-solid thixotropic technology is limited to the initial stage of development, and there are only a handful of semi-solid production equipment. We are now using a new type The semi-solid continuous manufacturing method, thixotropic squeeze casting, the current semi-solid continuous manufacturing processing method requires a continuous production device

Embodiment 1

[0031] Such as figure 1 As shown, a kind of semi-solid continuous feeding casting equipment proposed by the present invention includes a conveying device 1, a support frame 2, a primary heater 3, a secondary heater 4, a stainless steel crucible 5, a cleaning device 6, a spraying device 7, Thermocouple 8, closed pipe 9

[0032] The conveying device 1 is obliquely tilted, and a plurality of stainless steel crucibles 5 are fixed on it. The middle part of the conveying device 1 is provided with a primary heater 3 and a secondary heater 4. The secondary heater 4 is arranged close to the casting equipment. Two thermocouples 8 are provided; a closed pipe 9 is arranged inside the primary heater and the secondary heater, and the closed pipe 9 is wound with an inductor outside, and the stainless steel crucible 5 undergoes primary heating and secondary heating in the closed pipe. Wherein the length of the primary heater 3 is longer than that of the secondary heater 4 . The support fram...

Embodiment 2

[0035] The invention discloses a semi-solid continuous feeding casting method, which is carried out according to the following steps:

[0036] Step 1. The stepping motor drives the transmission wheel of the transmission device to work. During the transmission process, put the semi-solid billet into the stainless steel crucible;

[0037] Step 2. The crucible is transported to the primary heating zone, and the induction heating starts to work. The thermocouple above the rod performs feedback calculation on the measured aluminum rod temperature and reaches the preset temperature, and then it is transmitted to the secondary heating zone through a closed pipeline;

[0038] Step 3. The thermocouple above the bar in the secondary heating zone performs feedback calculation on the measured aluminum bar temperature and stops heating when it reaches the preset temperature;

[0039] Step 4. Pour the crucible into the barrel of the extruder in the way of turning over and pouring the materi...

Abstract

The invention discloses a semi-solid continuous feeding and casting device and method. The semi-solid continuous feeding and casting device comprises a delivery device, a first-stage heater, a second-stage heater, stainless steel crucibles, a cleaning device, a spraying device, thermocouples and enclosed pipelines. The delivery device tilts and is fixed with the multiple stainless steel crucibles.The middle of the delivery device is equipped with the first-stage heater and the second-stage heater. The second-stage heater is close to a casting device. The interior of each heater is provided with a thermocouple. The interiors of the first-stage heater and the second-stage heater are equipped with the enclosed pipelines. The stainless steel crucibles are subjected to primary heating operation and secondary heating operation in the enclosed pipelines. The invention provides a semi-solid fully-automated continuous production device which is capable of automatically heating, adding material, spraying and cleaning. By combining an inductive heating mode with the thermocouples, PID precise temperature control is performed so as to obtain required semi-solid blank within the temperature range. Due to the enclosed pipelines, the heating process is clean without any impurity. Meanwhile, heating temperature is kept.

Description

technical field [0001] The invention belongs to the field of casting, and more specifically relates to a novel semi-solid continuous feeding casting equipment, which is suitable for low-melting point alloys such as aluminum alloys, and is mainly used for die-casting production and extrusion continuous casting production. Background technique [0002] At present, Europe and the United States are the main areas for the research and application of semi-solid casting technology. In addition, Japan established a metal semi-solid processing development research company in the early years. Entering the 21st century, the application of semi-solid casting technology has gradually become a field that advanced industrial countries are competing to develop abroad, and is called a new generation of emerging metal forming technology by experts and scholars. After years of research and development, at present, aluminum and magnesium alloy semi-solid casting technology has entered the growt...
