Unshaped refractory Silica Refractory

►Silica hot patch refractory is a repair cement used to repair and seal door jambs in coke ovens.
Refractory cement for in situ hot repair of the sole of coke ovens. This material is supplied dry and mixed on site and pumped into the oven. It can be spread along a sole of the oven using recoke push bar and allow to self level. Maximum service temperature 1400°C.
White ready mixed, refractory air setting mortar. Maximum service temperature 1425°C. Refractory mortar is also as known as joint filler, it is composed of a certain particle ratio of refractory powder, binder and additive, pour water or liquid binder to tune into a paste. Silica mortar is an important part of refractory mortar which is as Cab-O-sil or adding some ganister sand as main raw materials, the binder adopts mild-clay or chemical bond.

►Application：
Silica mortar is mainly used for laying and repair of coke oven, hot blast stove, glass melting furnace, melting furnace and other masonry of high quality silica bricks industrial furnace.

►Features:
1.High adhesive strength.
2.High refractoriness.
3.Excellent refractoriness under load.
4.Good installation performance.

►Mixing sequence:
1. The silica mortar is the fine powder (0.088mm). Put the mortar in to the mixer and spray the small bag of additives on the dry powder evenly, mix them for 3 to 5min. Next, put 32 to 35 per cent of clean water (tap water and water amount can be adjusted according to actual conditions) into it and continue mixing for 5 to 10min. The effect will be better if you put the mortar slurry static for 10min. Amount of agitation should be determined according to the capacity of mixer. But it must be used by the bag.
2. The mortar well mixed should be used as soon as possible for fear of loosing effectiveness.
Attention: it is prohibited to put the additives into the water separately; it is prohibited to use acid industrial waste water to mix the slurry; operate strictly according to the requirements, or else it will influence the masonry quality and useful life of the mortar.

As adaptive case management (ACM) systems mature, we are moving beyond simple systems that allow knowledge workers to define ad hoc processes, to creating more intelligent systems that support and guide them. Knowledge workers still need to dynami-cally add information, define activities and collaborate with others in order to get their work done, but those are now just the table stakes in a world of big data and intelligent agents. To drive innovation and maintain operational efficiencies, we need to augment case work typically seen as relying primarily on human intelligence with machine intelligence. In other words, we need intelligent ACM.

Highly predictable work is easy to support using traditional programming techniques, while unpredictable work cannot be accurately scripted in advance, and thus requires the involvement of the knowledge workers themselves. The core element of Adaptive Case Management (ACM) is the support for real-time decision-making by knowledge workers.
