⑴加熱芯盒 芯盒用電或煤氣加熱。芯盒的加熱溫度由殼芯砂粘結(jié)劑、需要的殼厚、結(jié)殼時(shí)間和硬化時(shí)間等因素確定，一般為260~280℃。
The box core box of the heating core is heated by electricity or gas. The heating temperature of the core box is determined by the factors such as core sand binder, shell thickness, crust time and hardening time, etc. Generally, it is 260 ~ 280 C.
⑵吹砂 殼芯砂的流動(dòng)性好，因此吹砂斗內(nèi)只需通入0.1~0.3MPa的低壓壓縮空氣進(jìn)行吹砂，并在一定時(shí)間內(nèi)（1~3s）保持壓力。掌握好吹砂壓力和保持時(shí)間適當(dāng)，有利于獲得輪廓清晰、完整和光潔的砂芯。
(2) sand blowing sand core sand fluidity is good, so the sand blowing bucket only need to enter the 0.1~0.3MPa low pressure compressed air to blow sand, and in a certain time (1~3s) to maintain pressure. Good control of sand blowing pressure and holding time is beneficial to obtain clear, intact and clean sand cores.
⑶結(jié)殼 吹砂結(jié)束后，吹砂斗停留一段時(shí)間進(jìn)行結(jié)殼，結(jié)殼時(shí)間一般為15~50s，殼厚按需要而定，一般為3~10mm。
_Aftersand blowing, the sand blowing bucket stays for a period of time to crust. The crust time is generally 15-50s, and the shell thickness is generally 3-10mm.
⑷倒出余砂 達(dá)到規(guī)定的結(jié)殼厚度后，降砂斗翻轉(zhuǎn)180°，將未曾結(jié)殼的中心部分芯砂倒回吹砂斗。然后作左、右45°的搖擺，以倒凈未結(jié)殼的芯砂。
_Whenthe remaining sand reaches the required crust thickness, the bucket flips 180 degrees, and the core sand of the center part without crust is reversed to the sand blowing bucket. Then the left and right 45 degree swings are used to pour out the core sand without crust.
⑸硬化 將已結(jié)殼而尚處于塑性狀態(tài)的薄殼繼續(xù)加熱一段時(shí)間，使塑性薄殼完全硬化。硬化時(shí)間視殼厚而定，一般為2min左右。
Hardening will continue to heat the thin shell, which is already in a plastic state, for a period of time, so that the plastic shell can be completely hardened. The hardening time depends on the thickness of the shell, generally around 2min.
⑹頂芯、取芯 硬化結(jié)束，高強(qiáng)度的薄殼砂芯已經(jīng)制成，可從芯盒中頂出，用人工或?qū)Ｓ霉ぞ呷〕龃谩?br /> Core, core hardening, high-strength thin shell sand core has been made, can be ejected from the core box, with artificial or special tools to remove for use.
