A graphite crucible (2) for retaining a quartz crucible (1) has a graphite crucible substrate (3) as a graphite crucible forming material, and a coating film (4) made of a carbonized phenolic resin and formed over the entire surface of the graphite crucible substrate (3). The phenolic resin is impregnated inside open pores (5) existing in a surface of the graphite crucible substrate (3). The coating film (4) may be formed only within a portion of the graphite crucible in which SiC formation can occur easily, not over the entirety of the surface of the graphite crucible. For example, it is possible to deposit the film only on the entire inner surface of the crucible. It is also possible to deposit the film only on a curved portion (sharply curved portion) of the inner surface, or only on a curved portion and a straight trunk portion.

The invention relates to aluminum oxidation wastewater treatment and reclaimed water reuse technology, which is characterized in that the technology mainly comprises the steps of pretreatment, electric coagulation, micro-filtration and reverse osmosis; pretreating high fluoride-containing wastewater, ammonia-containing wastewater and nickel-containing wastewater respectively, and centralizedly draining the wastewater to a wastewater disposal basin with other production wastewater in a workshop; sending the wastewater into a pH adjustment tank, conveying the wastewater to an electric coagulation machine for electric coagulation treatment after the pH value is adjusted to be between 4 and 6, making the wastewater after the electric coagulation treatment enter an electric coagulation discharge bay, sending the wastewater to a micro-filtration concentration tank, conveying the wastewater to a micro-filtration system, and collecting a micro-filtration effluent to a reuse water basin; and conveying one part of water in the reuse water basin to the workshop for reuse, quantificationally draining one part, conveying the other part to a reverse osmosis system to produce pure water, and storing the pure water in a pure water storage tank. In sum, the technology can effectively remove heavy metals and salts in the wastewater, ensure that the COD in the treated wastewater is less than or equal to 25 mg / L, cannot cause secondary pollution of reuse water due to adding a coagulating agent and a flocculating agent, and has high reuse rate of reclaimed water.

The invention relates to a dynamic soft-measuring method of ingredients of regenerated flue gas generally regenerated by a catalytic cracking device, which belongs to the technical field of production process soft measurement. The method is characterized by comprising the following steps: utilizing a dynamic model of mechanism analysis of a regenerator to preliminarily estimate the mol flow of all main ingredients of the regenerated flue gas and the heat capacity of the regenerated flue gas; utilizing the heat balance of a CO incinerator to further estimate the CO content of the regenerated flue gas more accurately; returning the estimation value of the CO content into the dynamic model of the mechanism analysis of the regenerator, and calculating more accurate CO content; repeating the iterative algorithm, and estimating important immeasurable variables of the regenerator when the CO estimation value is converged. By jointly utilizing the dynamic model of the mechanism analysis of the regenerator and the heat balance of the external CO incinerator and adopting the combined way of an on-line and real-time process computing technology and a dynamic model observation technology, theinvention achieves the dynamic soft measurement of immeasurable variables of the regenerator in the catalytic cracking device and provides helps for safety production as well as energy saving and consumption reduction in important production processes.

Disclosed is an annealing apparatus which is provided with: a furnace body (2) having a cover part (2c) which makes it possible to expose the inside of the furnace body (2) and which also makes it possible to open an inlet opening (2a) and an outlet opening; and a conveyance device (6) which is disposed outside the furnace body (2) and conveys a sheet (S) by gripping part of said sheet (S). By means of this, the conveyance device is prevented from being exposed to a high-temperature environment, so the lifespan of the conveyance device can be increased.

The invention discloses a method for breeding propylaea japonica with semi-artificial feed. A co-feeding mode with the artificial feed and aphids is adopted, and the artificial feed is made of, by weight, 20-30 parts of water, 3-5 parts of layers of oriental armyworm powder, 1-3 parts of yeast powder, 1-3 parts of honey, 1-2 parts of aphid powder, 0.5-1.5 parts of sucrose, 0.2-0.4 part of agar, 0.02-0.06 part of olive oil, 0.02-0.06 part of ascorbic acid, 0.02-0.04 part of methylparaben, 0.02-0.04 part of potassium sorbate, 0.04-0.06 part of Webster salt and 0.005-0.015 part of multivitamin B.By adopting the method, propylaea japonica can grow, develop and breed normally under the condition of saving 71.3% natural baits, so that the production cost is reduced, and large-scale breeding expansion of propylaea japonica is achieved.
