中包烘烤应注意哪些问题?

答案

参考答案:

总的要求是在开浇前2小时,快速将水口、塞棒烘烤到1000~1100℃,中包内衬先小火烘烤30min,再大火烘烤90min以上。铝碳质制品在烘烤过程中,其强度变化规律是:随着烘烤温度的上升,其强度下降,到500~600℃时强度最低,当温度继继上升,春强度又增加,到1300℃左右恢复原状,再升高温度,其强度又下降,所以水口、塞棒应快速烘烤到1000~1100℃。

For hundreds of years, artists have used cartoons to criticize bad rulers or landowners. As early as the 19th century, people produced and read books of drawings. In many ways, they were similar to modern comics(漫画). They contained stories of naughty children and playful animals. The owl and the elephant were usually wise animals, ready to give advice. The lion and tiger were brave. The fox and wolf were cunning, greedy and dangerous.

A century ago, an American newspaper published the first-color comic strip. It was so popular that sales of the newspaper, Morning Journal, increased quickly. Since then, newspapers throughout the world have included comic strips.

In modern time, comics are popular in China, Japan, the USA and almost everywhere. Not even video games or CD-ROMs have reduced their popularity. Names such as Snoopy, Woodstock and Garfield are well known in dozens of countries. The Peanuts comic strip appears in over 2,000 newspapers and in more than 25 languages.

Perhaps one day, you may like to create your own comic strip and become a millionaire. First, you must think of a good plot. It should be funny, exciting or interesting in some way. It should have plenty of action. Moreover, the language must be realistic and simple. The words should suit the characters in your story.

Furthermore, the characters in your story must be clear to readers. They should be obviously good or bad. In many comic strips—especially those showing crime of adventure—there should also be a hero or heroine. This will attract the reader to keep on reading the story.
