Construction Service & Regulations
1.Check the size, specification, layout, installation and quality of the metal anchorage and make expansion
processing of the anchors.
2.Erect the formworks (hardwood or steel) in advance.
3.Unpacking and pouring the castable
4.Mixing
5.Installation of the mixed castables & Large area constrction
6.Vibrating
7.Before the castable block get final set,it can not bear any pressure or vibration.
8.Curing & Stripping
9.Baking the Furnaces (taking cement plant kiln as an example):
1). Keep the initial temperature at 20°C or so.
2). Please strictly follow the curve to conduct the baking work and increase the temperature smoothly and
evenly.
3). Lay out as many temperature measuring points as possible to monitor the temperature in the kiln, ensuring
the stable increase of the temperature.
