1.浇注工艺
    浇注工艺分为移动浇注和定点浇注两种类型。移动浇注是用行走式搅拌机将物料配好下到搅拌机内,一边搅拌一边移动,到达模位后将搅拌好的加气混凝土料浆注入模具。定点浇注则是将搅拌机固定在配料站下方,使模具移动到搅拌机旁边,接受搅拌机内已经搅拌好的加气混凝土料浆,然后模具再移动到指定地点继续完成其发气硬化过程。
2.浇注成型工艺的主要设施
    搅拌机的任务是接受并容纳加气混凝土物料,通过强力搅拌使全部物料在工艺规定的时间内充分混合均匀;利用搅拌器的机械作用和料浆高速流动的冲击力,使固体物料中的颗粒充分分散;使后加入的少量辅助材料如碱液、水玻璃、表面活性剂等和发气剂—铝粉能在很短的时间内迅速分散到料浆的各个部分,保证发气均匀。
    搅拌机由筒体、搅拌器和传动装置组成。影响搅拌机效率和搅拌效果的主要因素是:搅拌器型式、筒体构造、搅拌器与筒体的尺寸关系和搅拌器的转速。目前,实际采用的搅拌机主要是螺旋式搅拌机。这种搅拌机的筒体为一具有锅状筒体和封顶的圆筒,搅拌器呈螺旋状,在搅拌器外面套有支撑在筒底和筒壁上的导流筒。物料由上面进入,搅拌好料浆由筒底中部的卸料口排出。
    在搅拌器转动时,料浆在快速旋转的情况下,受离心力的作用沿筒底弧面向上翻腾,到达筒体顶部后向中心部抛落并立即在旋转的螺旋叶片形成的吸力下强制地往下拉,经过导流筒,推压到筒体底板上,在底板的遮挡下又重新上升。料浆如此快速地上下翻滚,使各部分均能受到有力的推压和牵拉。这对于粘度较大的料浆的搅拌是比较有利的,收到良好的效果。

1 . Casting process
    Casting process is divided into mobile and fixed-point cast two types of casting. Mobile mixer pouring is walking down to the material with a good mixer, while mixing while moving, mixing well after reaching mode bit aerated concrete slurry into the mold. Fixed point in pouring the ingredients stand mixer sucked beneath the die to move to the next mixer, mixing well to accept the mixer has been aerated concrete slurry, and then die and then move to the designated location to complete their hair air hardening process.
2 . Casting process of major facilities
    Mixer's task is to accept and allow the Naga gas concrete materials, all materials by powerful stirring within the time prescribed in the process fully mixed; the role and use of mechanical stirrer speed slurry flow impact, so that the particles of solid material in full dispersion; so after adding a small amount of auxiliary materials such as lye, sodium silicate, surfactants and gas evolution agents - aluminum powder in a very short time, the rapid spread to all parts of the slurry to ensure uniform gas evolution.
    Mixer from the cylinder, mixers and gear components. Affect the efficiency of the mixer and mixing effect of the main factors are: stirrer type, cylinder structure, the size relationship and cylinder mixer and agitator speed. Currently, the actual use of the main mixer is a spiral mixer. This mixer has a pot-shaped cylinder is a cylinder and the cylinder cap, spiral mixer, set out in blenders have supported in the cylinder at the end of the draft tube and the tube wall. Material from above to enter, mix well slurry discharge from the tube at the end of the central discharge port.
    In blender rotates, the slurry in the case of rapid rotation, centrifugal force by the end of the arc along the cylinder churn up, after reaching the top of the cylinder into the falling to the center and immediately form a rotating spiral blade under the force of the suction to pull down, after a draft tube, push the cylinder floor, in the bottom of the shade Dangxia rise again. Slurry rolling up and down so quickly, so that all parts can be a powerful push and pull. This viscosity of the slurry mix is more favorable, and received good results.
