预热

The condition of numerical simulation on extrusion deformation is that the extrusion ratio is 4100, preheating temperature of billet is 300450 ℃ and extrusion ram speed is 220 mm/s.

模拟采用的挤压变形条件为：挤压比4~100，锭坯预热温度300~450 ℃，挤压杆速度2~20 mm/s。

Compared to where technology in espresso is going today - individual group-cap boilers for each group, dual boiler, dual PID, heat exchanger pre-heating the brew boiler water and mix-valve fine tuning individual on the fly grouphead temperature controls - the heat exchange boiler/brew system is possibly at the limit of its capabilities and risks being left behind by these newer technologies.

对比今天意式浓缩咖啡机技术的发展-独立冲泡锅炉系统对于每个冲煮头，双锅炉，双锅炉PID，热交换冲煮之前的预热水和混合阀微调在不同的冲煮头上进行温度控制-热交换锅炉/冲煮系统是在处理他们能力受到限制或者是减低风险的时候留下了这个继续解决的新技术。

Therefore propose that we give ear to do under the warm-up, not in the new ear plugs on the large volume to listen to.

因此建议大家先给耳塞做下预热，不要在新的耳塞上用大的音量来听。

The company is located in Shanghai Chemical Industrial Zone in southern, mainly the production of boiler pipe attachment and accessory products - pile tip has passed ISO9001: 2000 quality system certification, more than twenty years for the production of boiler plant attachment, economizer, superheater, reheater, air preheater, such as supporting the entire Product.

公司座落于上海南部化学工业区，主要生产锅炉附件及管桩的配套产品--桩尖，已通过ISO9001：2000质量体系认证，多年来为二十多家电厂生产锅炉附件、省煤器、过热器、再热器、空气预热器等全配套产品。

The analysis method can be well used for reference to develop advanced heater with homogeneous energy distribution.

这种数值建模的量化分析方法为开发辐射加热预热装置提供了有益的借鉴和分析思路。

A partial linear method is used to deal with non homogeneous nonlinear equation of heat conduction.

当激光波长λ=1 0 6 μm、功率密度i0 =70 0W /cm2 ，预热温度T0=5 2 3K时，经过 0 7秒，表面温度度升到 12 90K左右，再结晶厚度约为 0 5 μm

Main factors that caused the low heat efficiency and high energy consumption were inadequate atomizing of heavy oil, low combustion air preheating temperature, high exhaust fume temperature and low insulating perfomance of furnace wall.

造成加热效率低、能耗高的主要原因有：重油雾化不充分，助燃空气预热温度低、排烟温度高、炉墙保温性能下降等。

The web paper is inputted by Mill Roll Stand, and after heated and regulating the moisture by the pre-heater, the paper is put into the Single Facer for shaping and then conglutinating with another top paper to form a single corrugated board. The single corrugated board is then transmitted by the overhead bridge conveyor to multiple heater to be reheated, after this the paper is to double facer for being heated and jointed, herein a continuous corrugated board is formed.

由原纸架输入卷形原纸，经过热缸机加热及调节湿度，进入单面瓦楞机，经过瓦楞机的滚轧成形，与另一面纸粘合成单面瓦楞纸，由天桥架传送，经多重预热器再次加热，经上浆机粘糊再至双面机加热贴合，此时连续的瓦楞纸板即已成形。

Corrugated board production line generally includes the following parts: Mill Roll Stand, Pre-heater, Auto Splicer, Single facer, Overhead bridge conveyor, Multiple heater for liner, Gluer, Double facer, Slitter scorer, Cutter, Down stacker, Boiler and etc.

瓦楞纸板生产线一般由下列设备构成：原纸架、热缸机、接纸机、单面瓦楞机、天桥架、多重预热器、上浆机、双面机、分纸压线机、横切机、堆码机、锅炉等设备组合而成。

The three-ply, five-ply, seven-ply, and multi-function corrugated cardboard production line mainly consist of the following equipment; Mill Roll Stand, Surface Paper Preheater , Single Facer, Conveying Span Bridge, Glue Application Machine, Double Facer, Slitter Scorer, Cut-off, Conveyer and Stacker, Heating System, Air compression system and Glue Making System, etc.

主要由纸架、面纸预热器、单面瓦楞机、天桥输送机、涂胶机、双面机、纵切压线机、横切机、堆码机以及加热系统、空气压缩系统、制胶系统、电气控制系统等主要设备组成。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
